iii, p. 375]. Except for Phylloxera, insects were very scarce on the 

 whole and were only occasionally reported. In Bessarabia Clysia 

 ambigiiella did more or less considerable damage in a few localities, 

 this moth being reported also from the government of Cherson. 

 Larvae of Polyphylla fxllo and of a species of Otiorrhynchus were 

 reported from Tamida ; in addition to handpicking the last-named 

 was controlled by spraying with 2-3% solution of barium chloride. 

 Eriophyes [Phytoptus] sp. appeared in May in the province of Don ; 

 powdering with sulphur had little or no effect on this mite. Poly- 

 chrosis {Endemis) hotrana and Eriophyes were controlled in x\strachan 

 by spraying with arsenate of lead and Paris green. In the region of 

 the Black Sea small numbers of Otiorrkynckus tvrca occurred, against 

 which spraying with barium chloride was effected, while Eriophyes sp. 

 was successfully controlled by removing and burning the infested 

 leaves.

It is stated that the Department of Agriculture has made arrange- 

 ments with the Moscow People's Banlc to purchase abroad, principally 

 in England, through the London Agency of the above Bank, various 

 insecticides, which may be required for the campaign against insect 

 pests in the current year.

This is a preliminary accomit of the conclusions arrived at from 

 studies on Coccobacillus acridiorum. The cultures used were received 

 by the author from the Pasteur Institute in Paris, from Argentina, and 

 from the Pasteur Institute in Algiers, and he is of opinion that these 

 represent distinct species of bacteria. From bacteriological observations 

 on crickets, various micro-organisms are always to be found in 

 different parts of the body, even in those not connected with the 

 intestines. The uninterrupted passagss from one individual to 

 another as recommended by d'Herelle in order to increase the virulence 

 of the virus, even should the blood of insects be used for this, do 

 not exclude the possibility of a change in its identity. Owing to the 

 variety of cultures in circulation, the author suggests that they should 

 not be used in practice until it has been established that a genuine 

 culture exists and that it possesses qualities pathogenic to Locnsta, 

 niigratoria.
